Problem also exists with Electronic companies in general as well. IE. Pioneer not honoring their warranties on defective Kuro displays...

Also let this be a warning!

Never, never, buy a first generation Apple product unless your two steps away from a Apple Store, got cart blanche and a lot of time and money to spare. Certainly buy Apple Care, because after the first year, they drop you good.

Apple likes to innovate and unfortunately doesn't test any of it's products before release, rather relying upon the "surprise" and hype factor and cleaning up the mistakes later on if not at all.

Also the second and third generation has a more mature product offering, better processor, features, etc.


And yes I'm still on Leopard, because we called it Leoptard for the first 8 months out of the gate.

The Snow Leopard "guest deletion" problem is proof it's better to wait for things to get a bit solid before committing.




I've done enough beta testing for Apple over the years, my heart just isn't into it anymore, it's not making me money, so why bother?

Yes it is usually best to wait. Apple most definitely does test their products though. Unfortunately a limited sampling cannot over all the potential problems that may occur during mass production. On the other hand, I'd rather buy a first gen product from Apple than from HP (as an example) because I know they will suport it if something goes wrong. HP on the other hand will continue to knowingly put defective motherboards in laptops and not extend the warranties of all laptops affected by this practice.

And I forgot to ask solipsism, does this mean that although perhaps a later version has some flaws that it still is not an improvement on the original?
The part of my argument I left out was that very rarely is a product update a total disaster to be avoided at all costs. Sometimes there are glitches, but overall it is far more likely that an update to an existing line is better than the preceding version.

Good point, Dell either. My wife had a 600M that needed over the course of its two (three maybe?) year warranty four motherboards. The DC charging board was soldered to the motherboard, and it came loose every so often and wouldn't charge. Dell never came up with a fix, they just sent a guy out to replace the motherboard.
Until the warranty was over, that is. Knowingly defective (or design flaw, whatever) they probably could have saved a bundle by offering us a newer version, or a refund. Hell, if they did that my wife would probably still insist on a Dell computer.

Edit: price incorrect so removed....I was thinking of our 8200 tower... :/

No, it hasn’t, and you “non-glare iMac” is made in China and other asian countries. Crack it open and look at the stickers.

You misunderstood my previous post. It wasn’t about potentially having flaws and waiting for the revision to have them ironed out, it was about potentially having changes that may make me hold onto my current Mac for an extra revision. For example, I know both the latest MBP without realizing that Apple removed the EC/34 on all but the 17” model. The system has the same name and the unibody is essentially the same but there are differences that may make the purchase less than ideal for a buyer. Same goes for the dropping of FW400 from all devices. If you really need FW then you’ll have to stick with what you have or go with a machine with FW800. If one isn’t going to research the products they are buying then i don’t want to hear them bitching about them.

To my displeasure, my i5 27" iMac has flickered a couple times this morning, since the firmware update. Not a lot and I did not see that dip to black and back that I used to occasionally get right after a flicker or two. So, maybe they're on the right track, anyway.

I put it to sleep and brought it back out and no flickers since, so far.

Seems to me that if it were a problem that could not be fixed by firmware, it would not respond so well to being put to sleep and immediately wakened. For example, if heat were causing a hardware problem, you would not think that a second or two of sleep would cool it off much.

Other than those rare flickers, this computer is fantastic.

I think the guy who suggests waiting to buy new Apple hardware -- or any new hardware -- until its been out a few months is absolutely right, though. But I seem to forget that when Apple comes out with something new and the lust in me begins to build. Maybe I can remember it when the tablet arrives next year? Probably not.

The cheaper computers have far more problems than the Apple products we read everything about. It is insane some of the problems which I've seen HP and Dell hit the market with; sometimes critical hardware or DoA issues which do not lead to any sort of reaction from the company beyond 'return it to the store and get another one'. Even worse are some of the overheating problems which have come and gone from models. Those ruin computers in time ranges that easily fall outside warranty.

Nobody cares enough to start an HPInsider website, though, so there's no real publicity. Anything abnormal about Apple is widely publicized because it generates traffic. It is important to consider events like this from a realistic perspective.

Encoding 500+ frames per second h.264 video in Handbrake for the iPhone

Priceless...


I call BS. Sorry. My i7 clean new system managed to encode a 26 min. MKV video file into the H.264 format in about 12 min., which is roughly 65 frames/second. The 500+ frame rate you mention is absurd. I can imagine a lossless uncompressed source video file encoding much faster, but not 10X faster than having to decode a compressed file and then encode it again.

Time will show. In my 20-ish years of working in IT (and most of it I was actually working in service & support) I can't recall seeing flickering caused by software issue. I did, however, see number of faulty screens, graphics cards and, actually, a handful of compatibility issues.

What makes me wonder is, if it is caused by software - how come not all computers with same hardware and software exhibit same issues..? Having only part of total number with problems usually points to a bad batch of specific component.

So it remains to be seen:

1 - is fix really and completely fixing problems.

2 - what was the cause for the problem and how is software update fixing it - hopefully they are not pulling Dell here, "fixing" a problem by sacrificing performance (or something silly like that).

He said for the iPhone, I've seen some pretty big numbers (300+ fps) on my i7 PC when encoding to a relatively low resolution. 500 might be high, but not out of the question. I haven't touched handbrake in a while, so I can't really determine how valid his claim is, but I wouldn't write it off as absurd.

It was actually encoding using the stock iPhone profile (with two pass enabled and ABR). Resolution is 480 x 208.

Second pass reported all 4 CPU's pegged at 100% and 500+ FPS. I get 60-90 fps on stock DVD resolutions like 720x368 -> H.264 depending on any filtering.

Somebody mentioned before that ATI/AMD may be surreptitiously punishing Apple for not using AMD cpu's in the new Mac lineup. I'm not so sure, but do you think that may be a possibility? That could explain the reason for a sofware update fixing the problem.

Have you tried HandBrake v0.9.4 on Snow Leopard with an i7 iMac with varying frame sizes and codecs? I dont your claims but I also dont doubt DJRumpys either. Both statements seem very likely to me depending on the output settings.

No, I don't think so. Using AMD graphics is still better than using AMD-nothing. It is not that Apple hasn't got other options - nVidia has more than capable hardware in the range of 4670 and 4850. If AMD did use such tactics, they would more likely loose Apple for good than force Apple to do everything-AMD... and AMD is not in position to loose strong customers \

For AMD, that would pretty much be digging their own grave.

Also, same question apply - if software was the cause, why did it not exhibit on every iMac from specific line? Identical computers with identical software bug should have identical issues...

My second problem is that of an electrostatic charge running through the aluminum of the system. Apple support was very good with this, and are sending me a new system. Hopefully the new one will be OK this time...

Besides those issues, I am very happy with my machine. Production errors occur on new lines of products, these things happen. At least Apple was very helpful in trying to resolve them as soon as possible.

I applied the fix and sadly it didn't help. My new 27" iMac is fortuantly on it's way. I just hope that it won't have the same problems!

I think someone posted that Apple indicated if the update doesn't resolve the problem, then a hardware warranty replacement would be necessary. However, I wonder if some of these issues could be due to some of the ATI chips coming to apple with an old/wrong firmware revision and this would explain a firmware update resolving the issue.

I helped my brother-in-law buy his first Mac, and it was a dual core 27" iMac. He does have one major complaint, and that is simply that AutoCad is not yet available for Mac OS. Unfortunately, this means that he is having to run in Windows most of the time since he is a draftsman. Personally, I'm surprised that his new iMac survived my drooling all over it.

So? Perhaps a lot of people decided not to be smug having a whopping 27" computer sitting on their desk in these rough times.

I went as for far as covering my Apple logo on my MacBook Pro with a Ubuntu one.

Sad to report that the firmware did NOT take care of the problem on my display. It was clean for a while, but now the flickering is even WORSE than before.

Dang.

.

True, they might have more than one issue there... though last time I had to update graphics firmware was in the time of GF2 cards - my GF2 MX worked fine with Win 98 but was black-screening on early XP.

It is not common, but it is possible.

My new I mac i7 is fine, and I haven't got any flash or screen issue.
That's say, I know too many people having problems. It's not marginal.
I wonder if we could make a poll to see the percentage of defective 27 inch I mac.

Received my 27",Quad Core i7, iMac a couple of weeks ago and the CPU fan was spinning out of control at max (sounded like a jet engine). The screen was also yellow across the bottom half and the thing wouldn't stay awake after being woken up.

I took it to the Apple Store and they were going to replace the power supply, logic board, CPU fan and several cables. I opted to have it replaced (middle of January).

Odd thing too, right now I'm running OS 10.4.11 on an 800MHz G4 and Adobe Illustrator CS1 was running faster than when I installed CS4-Illustrator and ran it on the brand new i7 iMac. I opened several large files on the i7-iMac that I was having troubles on my 800MHz-G4 and I had the same problems (rendering large 3D objects that I had created in Illustrator). I opened up Activity Monitor to what was going on and there was only 300MB of RAM being alloted to CS4-Illustrator (out of 8GB of RAM). Don't understand what was going on (and I'm not very techy). Will have to do further test when I get the replacement.

Got contacted from my Apple dealer today (as I didn't order the new 27" i7 through the Apple Store) and he confirmed me that the iMac (ordered on this past black friday) won't arrive until late January, because of hardware problems, that Apple is trying to fix. Anyway I see that they are shipping them with small delays on the online store, even though they are acknowledging the problems to users experiencing flickers (I see that many users got up to 2 replacement, and after the second replacement they got a full refund). I really hope they manage to fix this problem because otherwise those iMacs are the best Apple ever did and they could help Apple market share a lot!
